Development of Preoperative and Postoperative Self-evaluation of Gait Model for Female Patients who have Undergone Total Hip Arthroplasty: A Structural Equation Modeling Analysis

Abstract

Objective: Models for preoperative and postoperative self-evaluation of gait were developed to clarify the effects of the self-evaluation of gait and the factors affecting self-evaluation of gait in women who have undergone total hip arthroplasty (THA). Methods: An anonymous self-administered questionnaire survey was conducted twice before and 6 months after the operation in 80 female patients scheduled for THA for the treatment of osteoarthritis of the hip. he pre- and postoperative models were examined through structural equation modeling analysis. Results: Age, the ability to walk, and thoughts regarding claudication were found to affect preoperative self-evaluation of gait. Preoperative self-evaluation of gait affected thoughts regarding social life, the level of satisfaction with the hip joint, and postoperative public self-consciousness. The ability to walk and thoughts regarding claudication were shown to affect postoperative self-evaluation of gait. Postoperative self-evaluation of gait affected general health perception, self-esteem, thoughts regarding social life, and the level of satisfaction with the hip joint. Conclusion: As influenced and influencing factors were linked differently in preoperative and postoperative self-evaluation of gait in female patients with THA, preoperative and postoperative self-evaluation of gait should be assessed separately.
